'peripherally-connected' originates from the word 'periphery,' which comes from Greek, specifically the word 'periphereia,' where 'peri-' meant 'around' and 'pherein' meant 'to carry.'

'periphereia' transformed into the Latin word 'peripheria,' and eventually became the modern English word 'periphery,' leading to the formation of 'peripherally-connected.'

Initially, it meant 'related to the outer boundary,' but over time it evolved into its current meaning of 'connected to the outer edges or boundaries.'
